Detailed Description

In order to more clearly illustrate the embodiments of the present utility model or the technical solutions in the prior art, the present utility model will be briefly described below with reference to the accompanying drawings and the description of the embodiments or the prior art, and it is obvious that the following description of the structure of the drawings is only some embodiments of the present utility model, and other drawings can be obtained according to these drawings without inventive effort to a person skilled in the art. It should be noted that the description of these examples is for aiding in understanding the present utility model, but is not intended to limit the present utility model.

Examples:

as shown in fig. 1-3, the present embodiment provides a pair of fastening pliers for hemorrhoid ligation, including a first hemostatic forceps 1, a second hemostatic forceps 2 and an elastic thread, the second hemostatic forceps 2 includes a third forceps arm 201 and a fourth forceps arm 202, the third forceps arm 201 and the fourth forceps arm 202 are hinged, the third forceps arm 201 and the fourth forceps arm 202 each include a second forceps head 2021 and a second forceps handle 2022, tip ends of the second forceps head 2021 are provided with extension portions 2023, one sides of the two extension portions 2023 opposite to each other are provided with clamping half rings 2024, and when the third forceps arm 201 and the fourth forceps arm 202 move opposite to each other, the two clamping half rings 2024 can form a closed ring.

Specifically, as shown in fig. 1, the elastic thread is not substantially different from the elastic thread in the prior art, when in use, the elastic thread is sleeved on the root of the first hemostatic forceps 1, one end of the elastic thread for tightening the elastic thread is left outside the patient, and when the hemorrhoid is sleeved, the elastic thread is sleeved and tied on the hemorrhoid by tightening the elastic thread left outside the patient.

Further, when the third clamp arm 201 and the fourth clamp arm 202 move in opposite directions, the two clamp half rings 2024 can form a closed ring, the two clamp half rings 2024 are mutually matched and used for clamping the elastic coil and pushing the elastic coil to the root of the hemorrhoid by bypassing the upper section of the hemorrhoid, so that the elastic coil can be effectively prevented from falling off from the second hemostatic clamp 2 in the clamping process, the operation is convenient, and the inner walls of the two clamp half rings 2024 are smooth surfaces, and the elastic coil can be prevented from being damaged.

Furthermore, the elastic coil and the second hemostatic forceps 2 with the clamping semi-ring 2024 are matched with each other, so that the hemorrhoid can be simply, effectively and quickly sleeved, and the technical effect of improving the operation efficiency is achieved.
